Breakthrough in Perovskite Solar Module Development

-Researchers at the University of North Carolina at Chapel Hill have developed mini solar modules with perovskite cells treated with zinc trifluoromethane sulfonate, achieving record efficiency.

-The perovskite ink additive, zinc trifluoromethane sulfonate, improves reproducibility and reduces fabrication costs, making the modules cheaper.

-The addition of zinc salts, particularly Zn2, enhances device efficiency by passivating defects in perovskite films.

-Mini modules with aperture areas of 84 cm2 and 108 cm2 achieved power conversion efficiencies of 19.60% and 19.21%, respectively, the highest efficiency ever certified for modules of these sizes.

-The research, published in Nature Communications, highlights the potential for commercialization with advancements in equipment capable of handling larger module sizes.
